when we call we get shielding explained to us (again hmm) as if they are the only people in the world who are limited right now.
That must be galling for you to have to listen to again notanan2. However, in mitigation, these (probably older? possibly grandparents?) might well be scared.
They must be of the opinion that you’re not quite stepping up to the plate here - unlike their very helpful neighbours.
Okay.
Deep breaths.
Next time (and there WILL be a next time!) perhaps try empathising with them. Not OTT but sincerely talking about their situation and really LISTENING to their worries. Take a little more time with them. They might well be genuinely frightened deep down. They probably perceive that you lot are younger, can go out and are a bit blasé about their diminished circumstances.
We all certainly have MORE disposable TIME these days. I bet if you came up trumps here with a sympathetic and genuinely caring ear you’d find a better understanding between you all.
The fact that these relatives wrote to your children (? Their grandchildren) illustrates their perceptions of a more carefree life beyond their enforced perimeter.
Communication is key. Take some extra care and time. Really listen to their woes. Gently tell them too of your own worries, regards the anxiety of shopping and how stressful it is these awful days.
A better understanding on both sides, done with warmth, should make a huge difference.
Good luck. x
